See “Forward-Looking Statements.”

OVERVIEW

American Coastal Insurance Corporation is a holding company primarily engaged in commercial and personal property and casualty insurance business with investments in the United States. On July 10, 2023, we changed our corporate name from United Insurance Holdings Corp. to American Coastal Insurance Corporation. During the periods presented, we conducted our business principally through two wholly owned insurance subsidiaries: American Coastal Insurance Company (AmCoastal) and Interboro Insurance Company (IIC). Collectively, we refer to the holding company and all our subsidiaries, including non-insurance subsidiaries, as “ACIC,” which is the preferred brand identification for our Company.

Our Company’s primary source of revenue is generated from writing insurance in Florida and New York. Our target market in such areas consists of states where the perceived threat of natural catastrophe has caused large national insurance carriers to reduce their concentration of policies. We believe an opportunity exists for ACIC to write profitable business in such areas. During 2022, we also wrote commercial residential insurance in South Carolina and Texas; however, effective May 1, 2022, we no longer write in these states. In addition, during 2022, we wrote personal residential business in six other states; however on February 27, 2023, our former insurance subsidiary, United Property & Casualty Insurance Company (UPC) was placed into receivership with the Florida Department of Financial Services (the "DFS"), which divested our ownership of UPC. The events leading to receivership and results of this subsidiary, now included within discontinued operations, can be seen in Note 4 of the Notes to Consolidated Financial Statements below.

On May 9, 2024, the Company entered into a Stock Purchase Agreement (the "Sale Agreement") with Forza Insurance Holdings, LLC ("Forza") in which ACIC will sell and Forza will acquire 100% of the issued and outstanding stock of IIC. The aggregate purchase price for the shares will be equal to IIC's GAAP shareholder’s equity on the closing date. Closing is subject to customary closing conditions, including New York Department of Financial Services ("NYDFS") approval of Forza's application for acquisition of control, and NYDFS approval of a new rate and form filing. On February 13, 2025, Forza’s application to acquire IIC was approved by the NYDFS. The Company and Forza have agreed to close on April 1, 2025. Given IIC is our last remaining personal lines entity and represents the final step in our strategic shift to becoming a specialty commercial underwriter, IIC results of operations and assets and liabilities are captured within discontinued operations and can be seen in Note 4 of the Notes to Consolidated Financial Statements below.

We have historically grown our business through strong organic growth, complemented by strategic acquisitions and partnerships, including our acquisitions of AmCo Holding Company, LLC (AmCo) and its subsidiaries, including AmCoastal, in April 2017, and IIC in April 2016, and our strategic partnership with a subsidiary of Tokio Marine Kiln Group Limited (Tokio Marine), which formed Journey Insurance Company (JIC) in August 2018. Effective June 1, 2022, we merged JIC into AmCoastal, with AmCoastal being the surviving entity.

As a result of our risk appetite in 2024, our policies in-force increased by 0.9% from 22,848 policies in-force at December 31, 2023, to 23,060 policies in-force at December 31, 2024. These values include IIC policies in-force, whose results are captured within discontinued operations.

Our business is subject to the impact of weather-related catastrophes on our loss and loss adjustment expenses (LAE). Over the last three years, the frequency of these catastrophes has increased. As a result, we have experienced increased catastrophe losses incurred during the prior three years. During the years ended December 31, 2024, 2023 and 2022, five, two, and two named storms, respectively, made landfall in our geographic footprint, resulting in retained pre-tax catastrophe losses of $25,442,000, $729,000, and $57,906,000, respectively, excluding our former subsidiary, UPC. In addition, during 2022, we increased our loss and LAE reserves as a result of development trends from 2017’s Hurricane Irma, that indicated our ultimate gross loss estimate should be increased.

AMERICAN COASTAL INSURANCE CORPORATION

For the year ended December 31, 2024, we have consolidated our Operating and Underwriting Expenses and General and Administrative Expenses lines within our Consolidated Statements of Comprehensive Income into the General and Administrative Expenses line. This was done in an effort to align more closely with our peer group for comparability. Accordingly, we have recast our Consolidated Statements of Comprehensive Income for the years ended December 31, 2023 and 2022 to align with this format. We have also added a new note to our consolidated financial statements, Note 3, Disaggregation of Relevant Expense Captions, to provide the users of our financial statements with enhanced insight into this expense line.

The following discussion highlights significant factors influencing the consolidated financial position and results of operations of ACIC. In evaluating our results of operations, we use premiums written and earned, policies in-force and new and renewal policies by geographic concentration. We also consider the impact of catastrophe losses and prior year development on our loss ratios, expense ratios and combined ratios. In monitoring our investments, we use credit quality, investment income, cash flows, realized gains and losses, unrealized gains and losses, asset diversification and portfolio duration. To evaluate our financial condition, we consider our liquidity, financialstrength, ratings, book value per share and return on equity.

Consolidated Net Income (Loss)

(1) Loss ratio, net is calculated as losses and LAE net of losses ceded to reinsurers, relative to net premiums earned. Management uses this operating metric to analyze our loss trends and believes it is useful for investors to evaluate this component separately from our other operating expenses.

(2) Expense ratio is calculated as the sum of all operating expenses less interest expense relative to net premiums earned. Management uses this operating metric to analyze our expense trends and believes it is useful for investors to evaluate these components separately from our loss expenses.

(3) Combined ratio is the sum of the loss ratio, net and expense ratio. Management uses this operating metric to analyze our total expense trends and believes it is a key indicator for investors when evaluating the overall profitability of our business.

(4) Underlying combined ratio, a measure that is not based on GAAP, is reconciled above to the combined ratio, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in “Definitions of Non-GAAP Measures”, below.

(5) Included in both the expense ratio and the combined ratio is amortization expense predominately associated with the AmCo and IIC acquisitions, which cause comparative differences among periods.

DEFINITIONS OF NON-GAAP MEASURES

We believe that investors’ understanding of ACIC’s performance is enhanced by our disclosure of the following non-GAAP measures. Our methods for calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Combined ratio excluding the effects of current year catastrophe losses and prior year reserve development (underlying combined ratio) is a non-GAAP measure that is computed by subtracting the effect of current year catastrophe losses and prior year development from the combined ratio. We believe that this ratio is useful to investors, and it is used by management to highlight the trends in our business that may be obscured by current year catastrophe losses and prior year development. Current year catastrophe losses cause our loss trends to vary significantly between periods as a result of their frequency of occurrence and magnitude, and can have a significant impact on the combined ratio. Prior year development is caused by unexpected loss development on historical reserves. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our performance. The most directly comparable GAAP measure is the combined ratio. The underlying combined ratio should not be considered as a substitute for the combined ratio and does not reflect the overall profitability of our business.

Net loss and LAE excluding the effects of current year catastrophe losses and prior year reserve development (underlying loss and LAE) is a non-GAAP measure that is computed by subtracting the effect of current year catastrophe losses and prior year reserve development from net loss and LAE. We use underlying loss and LAE figures to analyze our loss trends that may be impacted by current year catastrophe losses and prior year development on our reserves. As discussed previously, these two items can have a significant impact on our loss trends in a given period. We believe it is useful for investors to evaluate these components both separately and in the aggregate when reviewing our performance. The most directly comparable GAAP measure is net loss and LAE. The underlying loss and LAE measure should not be considered a substitute for net loss and LAE and does not reflect the overall profitability of our business.

RESULTS OF OPERATIONS

Consolidated Results

Net income attributable to ACIC for the year ended December 31, 2024 decreased by $234,193,000 to $75,718,000, compared to net income of $309,911,000 for the year ended December 31, 2023. The decrease in net income was driven by the deconsolidation of our former subsidiary, UPC, resulted in a gain of $238,440,000 in 2023. Drivers of net income for 2024 include increased gross premiums earned during the year, increased net investment income, an increase in ceded premiums earned, favorable prior year loss development during the year, and decreased policy acquisition costs, as described below.

Revenues

Our gross written premiums increased by $12,096,000, or 1.9%, to $647,805,000 for the year ended December 31, 2024, from $635,709,000 for the year ended December 31, 2023. The breakdown of the year-over-year changes in both direct and assumed written premiums by state and gross written premium by line of business are shown in the table below.

(1) Assumed premium written for 2024 and 2023 primarily included commercial property business assumed from unaffiliated insurers.

(1) Only includes new and renewal homeowner, commercial and dwelling fire policies written during the year.

Ceded premiums earned increased by $21,995,000, or 6.4%, to $364,618,000 for the year ended December 31, 2024, from $342,623,000 for 2023. The increase is primarily driven by a $12,334,000 increase in ceded premiums earned from our quota share agreements. This increase is attributed to the change in AmCoastal’s quota share reinsurance coverage during 2024. We had quota share coverage in place at 40% for the first half of 2024 and 20% for the second half of the year, while in 2023 we had no coverage for the first half of the year and 40% coverage for the remainder of the year. This drove increased cessions over the twelve months ended December 31, 2024.

Net investment income increased by $12,495,000, or 150.5%, to $20,795,000 for the year ended December 31, 2024, from $8,300,000 for 2023, driven by increased interest income due to a substantial increase in holdings and higher interest rates year-over-year.

Net realized investment losses and net unrealized gains (losses) on equity securities increased by $7,847,000, or 131.3%, to a net gain of $1,872,000 for the year ended December 31, 2024, from a net loss of $5,975,000 for the year ended December 31, 2023, driven by decreased investment sales in 2024 resulting in decreased realized losses of $6,665,000 on our investment portfolio. During 2023 as a result of liquidity pressure from the receivership of our former subsidiary, UPC, we liquidated investments in a loss position. Please see cash flow for more information. The remainder of the change is related to our re-entering of the equity market during 2024, resulting in unrealized gains on the portfolio of $1,996,000.

Expenses

Expenses for the year ended December 31, 2024, increased $26,513,000, or 15.5%, to $197,061,000, from $170,548,000 for 2023. The increase in expenses was primarily due to an increase in loss and LAE as a result of Hurricane Milton making landfall in 2024, which caused a large increase in catastrophe losses due to the $20,500,000 retention incurred from the storm. The calculations of our combined loss ratios and underlying loss ratios are shown below.

(1) Underlying loss and LAE is a non-GAAP financial measure and is reconciled above to net loss and LAE, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in the “Definitions of Non-GAAP Measures” section, above.

The calculations of the Company’s expense ratios are shown below.

Loss and LAE increased by $22,641,000, or 48.5%, to $69,319,000 for the year ended December 31, 2024, from $46,678,000 for the year ended December 31, 2023. Loss and LAE expense as a percentage of net earned premiums increased 7.5 points to 25.3% for the year ended December 31, 2024, compared to 17.8% for the year ended December 31, 2023. In addition, during the year ended December 31, 2024, prior year reserve favorable development was lower on both catastrophe and non-catastrophe losses. Excluding catastrophe losses and reserve development, our gross underlying loss and LAE ratio for the year ended December 31, 2024 would have been 7.4%, a decrease of 0.3 points from 7.7% during the year ended December 31, 2023.

Policy acquisition costs decreased by $4,446,000, or 5.9%, to $70,990,000 for the year ended December 31, 2024, from $75,436,000 for the year ended December 31, 2023. The primary driver of the decrease was an increase in ceding commission income of $6,959,000, driven by the changes in the terms of our quota share reinsurance agreement described above. This was partially offset by increased external management fees of $1,745,000, which fluctuated in conjunction with the year-over-year increase in gross written premium.

General and administrative expenses increased by $7,197,000, or 19.2%, to $44,756,000 for the year ended December 31, 2024, from $37,559,000 for the year ended December 31, 2023, driven by increased overhead costs such as increased amortization of capitalized software totaling $2,836,000 and an increase in salaries totaling $1,522,000. In addition, we saw an increase in the use of third parties for audit, tax, and legal services, totaling $1,065,000 and $620,000, respectively.

We experienced favorable reserve development in the current year and its historical impact on our net loss and net underlying loss ratios is outlined in the following table.

(1) Underlying net loss and LAE Ratio is a non-GAAP measure and is reconciled above to the Consolidated net loss and LAE Ratio, the most directly comparable GAAP measure.

ANALYSIS OF FINANCIAL CONDITION

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our accompanying consolidated financial statements and related notes in Part II, Item 8 in this Form 10-K.

Investments

The primary goals of our investment strategy are to preserve capital, maximize after-tax investment income, maintain liquidity and minimize risk. To accomplish our goals, we purchase debt securities in sectors that represent the most attractive relative value, and we maintain a moderate equity exposure. Limiting equity exposure manages risks and helps to preserve capital for two reasons: first, bond market returns are less volatile than stock market returns, and second, should the bond issuer enter bankruptcy liquidation, bondholders generally have a higher priority than equity holders in a bankruptcy proceeding.

We must comply with applicable state insurance regulations that prescribe the type, quality and concentrations of investments our insurance subsidiaries can make; therefore, our current investment policy limits investment in non-investment-grade fixed maturities and limits total investment amounts in preferred stock, common stock and mortgage notes receivable. We do not invest in derivative securities.

Two outside asset management companies, which have authority and discretion to buy and sell securities for us, manage our investments subject to (i) the guidelines established by our Board of Directors and (ii) the direction of management. The Investment Committee of our Board of Directors reviews and approves our investment policy on a regular basis.

Our cash and investment portfolios totaled $540,811,000 at December 31, 2024, compared to $311,874,000 at December 31, 2023.

The following table summarizes our investments, by type:

We classify all of our investments as available-for-sale. Our investments as of December 31, 2024 and 2023 consisted mainly of U.S. government and agency securities, securities of investment-grade corporate issuers, mortgage-backed securities, and states, municipalities and political subdivisions. Our equity holdings as of December 31, 2024 consisted of mutual funds and common stock. We held no equities as of December 31, 2023. Most of the corporate bonds we hold reflected a similar diversification. At December 31, 2024, approximately 87.8% of our fixed maturities were U.S. Treasuries, or corporate bonds rated “A” or better, and 12.2% were corporate bonds rated “BBB” or “BB”.

Reinsurance

We follow the industry practice of reinsuring a portion of our risks. Reinsurance involves transferring, or "ceding", all or a portion of the risk exposure on policies we write to another insurer, known as a reinsurer. To the extent that our reinsurers are unable to meet the obligations they assume under our reinsurance agreements, we remain primarily liable for the entire insured loss under the policies we write.

Our catastrophe reinsurance coverage consists of three separate placements:

1.AmCoastal’s core catastrophe reinsurance program in effect June 1 through May 31, annually, which includes excess of loss and quota share treaties providing coverage for catastrophe losses from named or numbered windstorms;

2.AmCoastal’s all other perils catastrophe excess of loss agreement in effect January 1 through December 31, annually, which provides protection from catastrophe loss events other than named or numbered windstorms and earthquakes; and

3.IIC’s core catastrophe reinsurance program in effect June 1 through May 31, annually, which provides protection from all catastrophe losses.

This reinsurance protection is an essential part of our catastrophe risk management strategy. It is intended to provide our stockholders with an acceptable return on the risks assumed by our insurance entities, and to reduce the variability of earnings, while providing surplus protection. Although reinsurance agreements contractually obligate our reinsurers to reimburse us for the agreed-upon portion of our gross paid losses, they do not discharge our primary liability. In the event one or more of our reinsurers fail to fulfill their obligation, the surplus of our statutory entities may decline, and we may not be able to fulfill our obligation to policyholders, or we may not be able to maintain compliance with various regulatory financial requirements. Additionally, we face the risk that actual losses incurred from one or more catastrophic events may be above the modeled expected loss resulting in losses exceeding our reinsurance coverage, which may result in a decline in surplus, and as a result we may not be able to fulfill our obligations to policyholders, or we may not be able to maintain compliance with various regulatory financial requirements. The details of our programs and the likelihood of a catastrophic event exceeding these three coverages are outlined below.

AmCoastal’s core catastrophe reinsurance program provides occurrence-based coverage up to an exhaustion point of approximately $1,260,000,000 for a first occurrence and $1,610,000,000 in the aggregate. Under this program, our GAAP retention on a first event is $20,500,000 ($10,000,000 retained by AmCoastal under statutory accounting principles (STAT retained), $10,500,000 retained separately by our captive). We have purchased second and third event retrocession coverage, reducing our second and third event GAAP retentions to $13,000,000 ($10,000,000 STAT retained by AmCoastal, $3,000,000 retained separately by our captive). AmCoastal’s program provides sufficient coverage for approximately a 1-in-206-year return period, indicating that the probability of a single occurrence exceeding protection purchased is roughly 0.5%, estimated by equally blending the AIR and RMS catastrophe models using long-term catalogs including demand surge. AmCoastal’s program also provides sufficient coverage for a 1-in-100-year event followed by a 1-in-50-year event in the same treaty year, the probability of which is less than 0.1%. While we believe these catastrophe models are very good tools and their output provides reasonable proxies for the probability of exhausting our reinsurance protections, they are imperfect, so actual results could vary materially from those expected.

AmCoastal’s all other perils catastrophe excess of loss agreement provides protection from catastrophe loss events other than named windstorms and earthquakes up to $172,000,000 in the aggregate. This agreement provides sufficient coverage for a 1-in-450-year return period, indicating that the probability of a single occurrence exceeding protection purchased is no more than 0.2%.

IIC’s core catastrophe reinsurance program, which is reported under discontinued operations, provides coverage up to an exhaustion point of approximately $82,500,000 in the aggregate, with a retention of $2,500,000 per occurrence. Based on IIC’s probable maximum losses (PML), the program provides sufficient coverage for two 1-in-130-year events in the same season, indicating the probability of a single occurrence exceeding protection purchased is no more than 0.1%.

Effective December 15, 2023, we agreed to commute a private reinsurer’s share of core catastrophe reinsurance coverage and replace this gap in coverage with new coverage provided by one of our other private reinsurers. This transaction resulted in additional expense of approximately $6,300,000 for the year ended December 31, 2023, and a reduction in expense of approximately $6,300,000 and $15,700,000 during the three and six months ended June 30, 2024, respectively.

41

AMERICAN COASTAL INSURANCE CORPORATION

Where we think prudent, particularly where premium rates are high relative to the risk, we retain risk whereby AmCoastal purchases reinsurance from Shoreline Re, our captive reinsurance entity. Shoreline Re participates on AmCoastal's all other perils catastrophe excess of loss agreement and AmCoastal's excess per risk agreement. In addition, Shoreline Re participates in a 30% quota share agreement with AmCoastal, which provides coverage for all catastrophe perils as well as attritional losses incurred.

The table below outlines the participation of Shoreline Re for each program, including premium received and capital at risk.

(1) Capital at risk is calculated by taking the aggregate losses Shoreline Re is subject to under the contract, less net premiums earned under the contract.

(2) This treaty provides or provided coverage for all catastrophe perils and attritional losses incurred. For all catastrophe perils, the quota share agreement provides or provided ground-up protection, effectively reducing our retention for catastrophe losses.

(3) Net premiums earned based on estimated subject premiums at 06/01/2024.

The table below outlines our quota share agreements in effect for the years ended December 31, 2024 and 2023. The impacts of these quota share agreements on the financial statements of our former subsidiary, UPC, are included in discontinued operations in 2023 and 2022.

(1) This treaty provides or provided coverage for all catastrophe perils and attritional losses incurred. For all catastrophe perils, the quota share agreement provides or provided ground-up protection, effectively reducing our retention for catastrophe losses.

(2) The cession rate of this treaty is reduced from 20% to 15% effective 06/01/2025 - 06/01/2026.

(3) This treaty provided coverage on our in-force, new and renewal policies until these states were transitioned to HCPCI and TypTap upon renewal.

Reinsurance costs as a percentage of gross earned premium during the years ended December 31, 2024 and 2023 were as follows:

AMERICAN COASTAL INSURANCE CORPORATION

See Note 10 in our Notes to Consolidated Financial Statements for additional information regarding our reinsurance program.

Unpaid Losses and Loss Adjustments

We generally use the term “loss(es)” to collectively refer to both loss and LAE. We establish reserves for both reported and unreported unpaid losses that have occurred at or before the balance sheet date for amounts we estimate we will be required to pay in the future, including provisions for claims that have been reported but are unpaid at the balance sheet date and for obligations on claims that have been incurred but not reported at the balance sheet date. Our policy is to establish these loss reserves after considering all information known to us at each reporting period. At any given point in time, our loss reserve represents our best estimate of the ultimate settlement and administration costs of our insured claims incurred and unpaid.

Unpaid losses and LAE totaled $322,087,000 and $347,738,000 as of December 31, 2024 and 2023, respectively. In addition, unpaid losses related to IIC totaled $21,499,000 and $22,483,000 as of December 31, 2024 and 2023, respectively, which have been classified as discontinued operations.

Since the process of estimating loss reserves requires significant judgment due to a number of variables, such as fluctuations in inflation, judicial decisions, legislative changes and changes in claims handling procedures, our ultimate liability will likely differ from these estimates. We revise our reserve for unpaid losses as additional information becomes available, and reflect adjustments, if any, in our earnings in the periods in which we determine the adjustments are necessary.

See Note 11 in our Notes to Consolidated Financial Statements for additional information regarding our losses and LAE.

Discontinued Operations

On February 10, 2023, we announced that a solvent run-off for UPC was unlikely and on February 27, 2023, UPC was placed into receivership with the DFS, which divested our ownership of UPC. As a result, UPC, as well as the activities related directly to supporting the business conducted by UPC, qualify as a discontinued operation. For more information regarding the results of our discontinued operations, see Note 4 in our Notes to Consolidated Financial Statements.

In addition, on May 9, 2024, the Company entered into a Sale Agreement with Forza in which ACIC will sell and Forza will acquire 100% of the issued and outstanding stock of IIC. The aggregate purchase price for the shares will be equal to IIC's GAAP shareholders' equity on the closing date. Closing is subject to customary closing conditions, including NYDFS approval of Forza's application for acquisition of control, and NYDFS approval of a new rate and form filing. On February 13, 2025, Forza’s application to acquire IIC was approved by the NYDFS. The Company and Forza have agreed to close on April 1, 2025. A comparison of the results of IIC's operations for the years ended December 31, 2024 and 2023 can be seen below.

IIC Year-over-Year Results

Net loss attributable to IIC for the year ended December 31, 2024 decreased $1,687,000, or 56.1%, to $1,319,000 from $3,006,000 for the same period in 2023. The details of the revenues and expenses that drove this change are outlined below.

Revenue

IIC gross written premiums increased $5,370,000, or 15.6%, to $39,704,000 for the year ended December 31, 2024 from $34,334,000 for the same period in 2023. This increase was driven primarily by rate increases. The change in IIC gross written premiums and new and renewal policies year-over-year can be seen below.

(1) Only includes new and renewal homeowner and dwelling fire policies written during the year.

AMERICAN COASTAL INSURANCE CORPORATION

Net investment income decreased by $181,000, or 8.0%, to $2,093,000 for the year ended December 31, 2024 from $2,274,000 for 2023, driven by decreased interest income due to decreased holdings year-over-year.

Expenses

Expenses attributable to IIC for the year ended December 31, 2024 increased $3,909,000, or 14.9%, to $30,172,000 from $26,263,000 for the same period in 2023. The increase in expenses was primarily due to an increase in our loss and LAE incurred during 2024, driven by increased current year non-catastrophe losses incurred. The details of these changes can be seen below.

The calculations of our loss ratios and underlying loss ratios are shown below.

(1) Underlying loss and LAE is a non-GAAP measure and is reconciled above to net loss and LAE, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this document is in the "Definitions of Non-GAAP Measures" section of this Form 10-K.

The calculations of our expense ratios are shown below.

Loss and LAE attributable to IIC increased $2,555,000, or 15.8%, to $18,738,000 for the year ended December 31, 2024 from $16,183,000 for the same period in 2023. Loss and LAE expense as a percentage of net earned premiums decreased 10.4 pts to 71.2% for the year ended December 31, 2024, compared to 81.6% for the same period in 2023. Excluding catastrophe losses and prior year reserve development, our gross underlying loss and LAE ratio for the year ended December 31, 2024 was 51.2%, an increase of 8.7 pts from 42.5% during the year ended December 31, 2023.

Policy acquisition costs attributable to IIC increased $426,000, or 5.4%, to $8,336,000 for the year ended December 31, 2024 from $7,910,000 for the same period in 2023. The primary driver of the increase was an increase in agent commissions and credit card processing fees of $138,000 and $332,000, respectively, both of which vary with changes in gross written premium year-over-year. The increase in agent commissions was partially offset by a decrease in commission rate from 20% to 15% effective January 1, 2024.

General and administrative expenses attributable to IIC increased $928,000, or 42.8%, to $3,098,000 for the year ended December 31, 2024 from $2,170,000 for the same period in 2023, driven by an increase in salary-related expenses of $579,000 and an increase in external professional service costs, such as legal and audit fees, totaling $350,000.

LIQUIDITY AND CAPITAL RESOURCES

We generate cash through premium collections, reinsurance recoveries, investment income, the sale or maturity of invested assets, the issuance of debt and the issuance of additional shares of our stock. We use our cash to pay reinsurance premiums, claims and related costs, policy acquisition costs, salaries and employee benefits, other expenses and stockholder dividends, acquire subsidiaries and pay associated costs, as well as to repay debt and purchase investments.

As a holding company, we do not conduct any business operations of our own and, as a result, we rely on cash dividends or intercompany loans from our management subsidiaries to pay our general and administrative expenses. Insurance regulatory authorities heavily regulate our insurance subsidiaries, including restricting any dividends paid by our insurance subsidiaries and requiring approval of any management fees our insurance subsidiaries pay to our management subsidiaries for services rendered; however, nothing restricts our non-insurance company subsidiaries from paying us dividends other than state corporate laws regarding solvency. Our management subsidiaries pay us dividends primarily using cash from the collection of management fees from our insurance subsidiaries, pursuant to the management agreements in effect between those entities. In accordance with state laws, our insurance subsidiaries may pay dividends or make distributions out of that part of their statutory surplus derived from their net operating profit and their net realized capital gains. The risk-based capital (RBC) guidelines published by the National Association of Insurance Commissioners (NAIC) may further restrict our insurance subsidiaries’ ability to pay dividends or make distributions if the amount of the intended dividend or distribution would cause their respective surplus as it regards policyholders to fall below minimum RBC guidelines. See Note 16 in our Notes to Consolidated Financial Statements and Part II, Item 5 for additional information.

During the year ended December 31, 2024, the Company made capital contributions of $1,265,000 to its reinsurance subsidiary, Shoreline Re. We may make future contributions of capital to our insurance subsidiaries as circumstances require. During the year ended December 31, 2023, we made no capital contributions to our subsidiaries. During the year ended December 31, 2022, we contributed $81,000,000 and $11,200,000 to our former insurance subsidiaries, UPC and FSIC, respectively. The contribution made to FSIC was made prior to the merging of FSIC into UPC. In addition, we contributed $9,574,000 to our reinsurance subsidiary, Shoreline Re.

During December 2024, we received a $14,300,000 dividend from our insurance subsidiary, AmCoastal. During 2022, we received a dividend of $26,000,000 from AmCoastal.

In September 2023, the Company entered into an equity distribution agreement (the “Agreement”) with Raymond James & Associates, Inc., as agent (the “Agent”), of up to 8,000,000 shares of the Company’s common stock, par value $0.0001 per share (the “Shares”). Sales of the Shares under the Agreement will be made in sales deemed to be “at the market offerings”. The Agent is not required to sell any specific amount of Shares but has agreed to act as the Company’s sales agent for a commission equal to 3.0% of the gross proceeds from the sales of the Shares. As of December 31, 2024, 4,373,000 shares had been sold under the Agreement resulting in commissions paid of approximately $1,181,000 and net proceeds of approximately $38,190,000. The Agreement will terminate upon the issuance and sale of all Shares subject to the Agreement, or the Agreement may be suspended or discontinued at any time.

On December 13, 2017, we issued $150,000,000 of senior notes (Senior Notes) that will mature on December 15, 2027 and bear interest at a rate equal to 6.25% per annum payable semi-annually on each June 15 and December 15, commencing June 15, 2018. The Senior Notes are senior unsecured obligations of the Company. We may redeem the Senior Notes at our option, at any time and from time to time in whole or in part, at a redemption price equal to the greater of (i) 100% of the principal amount of the Senior Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon from the date of redemption to the date that is three months prior to maturity. On and after that date, we may redeem the Senior Notes at par. On December 8, 2022, the Kroll Bond Rating Agency, LLC announced a downgrade of our issuer and debt ratings from BBB- to BB+. As a result, pursuant to our agreement, the interest rate of our Senior Notes increased from 6.25% to 7.25% effective on June 15, 2023.

As a result of claim activity from the current and prior years, we have an obligation related to the unpaid policyholder losses and unpaid LAE associated with the settling of these claims. As of December 31, 2024, our total obligation related to these claim payments was $322,087,000, of which we estimate $124,642,000 to be short-term in nature (due in less than twelve months), based upon our cumulative claims paid over the last 23 years. This value includes IIC, which is classified as discontinued operations but is still our obligation until the sale of the entity is complete. While we believe that historical performance of loss payment patterns is a reasonable source for projecting future claim payments, there is inherent uncertainty in these estimated projected settlements, and as a result these estimates will differ, perhaps significantly, from actual future payments.

47

AMERICAN COASTAL INSURANCE CORPORATION

In addition to our unpaid loss and LAE, as of December 31, 2024, we have outstanding debt obligations related to our notes payable totaling $150,000,000. This is exclusive of interest costs, which we estimate will total $43,500,000 over the life of the debt, based on the current fixed interest rates of these notes. Our short-term obligation related to these notes payable total $10,875,000 in estimated interest payments and no principal payments. For more information regarding these outstanding notes, please see Note 12 in our Notes to Consolidated Financial Statements.

In connection with entering into contracts with our outside vendors, we have minimum obligations due to our vendors over the life of the contracts. Our main vendor obligations are related to underwriting tools, claims and policy administration systems. Our total obligation related to these two categories of obligations are $1,605,000, and $525,000, respectively. Of these obligations, $1,605,000, and $225,000, respectively are short-term in nature.

Cash Flows for the Year Ended December 31, (in millions)

Operating Activities

The principal cash inflows from our operating activities come from premium collections, reinsurance recoveries and investment income. The principal cash outflows from our operating activities are the result of claims and related costs, reinsurance premiums, policy acquisition costs and salaries and employee benefits. A primary liquidity concern with respect to these cash flows is the risk of large magnitude catastrophe events.

During the year ended December 31, 2024, we experienced cash inflows of $243,509,000 compared to outflows of $136,003,000 during the year ended December 31, 2023. This change was driven by changes in our operating assets and liabilities of $398,841,000, offset by a decrease in net income, net of adjustments to reconcile net income to cash of $19,329,000. The change in our operating assets and liabilities is attributed to the placement of UPC into receivership in 2023 as a result of the loss above, divesting our ownership of UPC during 2023.

Investing Activities

The principal cash inflows from our investing activities come from repayments of principal, proceeds from maturities and sales of investments. We closely monitor and manage these risks through our comprehensive investment risk management process. The principal cash outflows relate to purchases of investments. Additional cash outflows relate to the purchase of fixed assets. The primary liquidity concerns with respect to these cash flows are the risk of default by debtors and market disruption. During the year ended December 31, 2024, cash used in investing activities increased $176,667,000, driven by the purchases of fixed maturities.

Financing Activities

The principal cash inflows from our financing activities come from issuances of debt and other securities. The principal cash outflows come from repayments of debt and payments of dividends. The primary liquidity concern with respect to these cash flows is market disruption in the cost and availability of credit. We believe our current capital resources, together with

48

AMERICAN COASTAL INSURANCE CORPORATION

cash provided from our operations, are sufficient to meet currently anticipated working capital requirements. During the year ended December 31, 2024, cash used in financing activities increased by $40,609,000 to cash used of $13,840,000 from proceeds of $26,769,000. This was due primarily to $24,102,000 in dividends declared during 2024 and a decrease in proceeds from the issuance of common stock of $15,172,000 year-over-year.

RECENT ACCOUNTING STANDARDS

Please refer to Note 2(v) in our Notes to Consolidated Financial Statements for a discussion of recent accounting standards that may affect us.

APPLICATION OF CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported in the consolidated financial statements. The most critical estimates include those used in determining:

•reserves for unpaid losses,

•fair value of investments,

•investment portfolio credit allowances, and

•goodwill.

In making these determinations, management makes subjective and complex judgments that frequently require estimates about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance industry. It is reasonably likely that changes in these estimates could occur from time to time and result in a material impact on our consolidated financial statements.

In addition, the preparation of our financial statements in accordance with GAAP prescribes when we may reserve for particular risks, including litigation exposures. Accordingly, our results for a given reporting period could be significantly affected if and when we establish a reserve for a major contingency. Therefore, the results we report in certain accounting periods may appear to be volatile and past results may not be indicative of results in future periods.

Reserves for Unpaid Losses and LAE

Reserves for unpaid losses and LAE represent the most significant accounting estimate inherent in the preparation of our financial statements. These reserves represent management’s best estimate of the amount we will ultimately pay for losses, and we base the amount upon the application of various actuarial reserve estimation techniques as well as other material facts and circumstances known at the balance sheet date.

As discussed in Note 11 in our Notes to Consolidated Financial Statements, we determine our ultimate losses by using multiple actuarial methods to determine an actuarial estimate within a relevant range of indications that we calculate using generally accepted actuarial techniques. Our selection of the actuarial estimate is influenced by the analysis of our historical loss and claims experience since inception. For each accident year, we estimate the ultimate incurred losses for both reported and unreported claims. In establishing this estimate, we reviewed the results of various actuarial methods discussed in Note 11 in our Notes to Consolidated Financial Statements.

Fair Value of Investments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We are responsible for the determination of fair value of financial assets and the supporting assumptions and methodologies. We use quoted prices from active markets and an independent third-party valuation service to assist us in determining fair value. We obtain only one single quote or price for each financial instrument.

49

AMERICAN COASTAL INSURANCE CORPORATION

As discussed in Note 5 in our Notes to Consolidated Financial Statements, we value our investments at fair value using quoted prices from active markets, to the extent available. For securities for which quoted prices in active markets are unavailable, we use observable inputs such as quoted prices in inactive markets, quoted prices in active markets for similar instruments, benchmark interest rates, broker quotes and other relevant inputs. We also have investments in limited partnerships that require us to use the net asset value per share method of valuation to determine fair value.

See “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” for more information regarding the sensitivity of our fixed maturity portfolio to changes in interest rates.

Investment Portfolio Credit Allowances

For investments classified as available for sale, the difference between fair value and cost or amortized cost for fixed income securities is reported as a component of accumulated other comprehensive income (loss) on our Consolidated Balance Sheets and is not reflected in our net loss of any period until reclassified to net loss upon the consummation of a transaction with an unrelated third party. We have a portfolio monitoring process to identify and evaluate each fixed income security whose carrying value may be impaired as the result of a credit loss.

For each fixed-income security in an unrealized loss position, if we determine that we intend to sell the security or that it is more likely than not that we will be required to sell the security before recovery of the cost or amortized cost basis for reasons such as liquidity needs, contractual or regulatory requirements, the security’s entire decline in fair value is recorded in earnings.

If our management decides not to sell the fixed-income security and it is more likely than not that we will not be required to sell the fixed-income security before recovery of its amortized cost basis, we evaluate whether the decline in fair value has resulted from credit losses or other factors. This is typically indicated by a change in the rating of the security assigned by a rating agency, and any adverse conditions specifically related to the security or industry, among other factors. If the assessment indicates that a credit loss may exist, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses will be recorded in earnings. Credit loss is limited to the difference between a security’s amortized cost basis and its fair value. Any additional impairment not recorded through an allowance for credit losses is recognized in other comprehensive income (loss).

If the estimated recovery value is less than the amortized cost of the security, a credit loss exists and an allowance for the difference between the estimated recovery value and amortized cost is recorded in earnings. The portion of the unrealized loss related to factors other than credit remains classified in accumulated other comprehensive income (loss). If we determine that the fixed income security does not have sufficient cash flow or other information to estimate a recovery value for the security, we may conclude that the entire decline in fair value is deemed to be credit related and the loss is recorded in earnings.

Due to the adoption of Accounting Standards Update (ASU) 2016-01 (ASU 2016-01) as of January 1, 2018, equity securities are reported at fair value with changes in fair value, including impairment write-downs, being recognized in the revenue section of our Consolidated Statements of Comprehensive Income (Loss).

See Note 2(b) in our Notes to Consolidated Financial Statements for further information regarding our credit loss testing.

Measurement of Goodwill and Related Impairment

Goodwill is the excess of cost over the estimated fair value of net assets acquired. Goodwill is not amortized but is tested for impairment at least annually or more frequently if events or circumstances, such as adverse changes in the business climate, indicate that there may be justification for conducting an interim test. We test goodwill for impairment by performing a quantitative assessment. Goodwill is impaired when it is determined that the carrying value of a reporting segment is in excess of the fair value of that reporting segment. The valuation methodologies utilized are subject to key judgments and assumptions that are sensitive to change. Estimates of fair value are inherently uncertain and represent only management’s reasonable expectation regarding future developments.

Please refer to Note 2(k) and Note 9 in our Notes to Consolidated Financial Statements for further information regarding our measurement of Goodwill and Related Impairment.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing in Part II, Item 8 of this Form 10-K. The following discussion provides an analysis of our results of operations and financial condition for 2023 as compared to 2022. Discussion regarding our results of operations and financial condition for 2022 as compared to 2021 is included in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021 and the Revised Items of our Form 10-K for the year ended December 31, 2022, filed as Exhibit 99.1 to Form 8-K on September 19, 2023. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Actual results may differ materially from those expressed or implied in these forward-looking statements as a result of certain known and unknown risks and uncertainties. See “Forward-Looking Statements.”

OVERVIEW

American Coastal Insurance Corporation is a holding company primarily engaged in commercial and personal property and casualty insurance business with investments in the United States. On July 10, 2023, we changed our corporate name from United Insurance Holdings Corp. to American Coastal Insurance Corporation. During the periods presented, we conducted our business principally through two wholly-owned insurance subsidiaries: American Coastal Insurance Company (AmCoastal) and Interboro Insurance Company (IIC). Collectively, we refer to the holding company and all our subsidiaries, including non-insurance subsidiaries, as “ACIC,” which is the preferred brand identification for our Company.

Our Company’s primary source of revenue is generated from writing insurance in Florida and New York. Our target market in such areas consists of states where the perceived threat of natural catastrophe has caused large national insurance carriers to reduce their concentration of policies. We believe an opportunity exists for ACIC to write profitable business in such areas. During 2022, we also wrote commercial residential insurance in South Carolina and Texas, however, effective May 1, 2022, we no longer write in these states. In addition, during 2022 we wrote personal residential business in six other states, however on February 27, 2023, our former insurance subsidiary, United Property & Casualty Insurance Company (UPC) was placed into receivership with the Florida Department of Financial Services (the "DFS"), which divested our ownership of UPC. The events leading to receivership and results of this subsidiary, now included within discontinued operations, can be seen in Note 3 of the Notes to Consolidated Financial Statements below.

We have historically grown our business organically, complemented by strategic acquisitions and partnerships, including our acquisitions of AmCo Holding Company, LLC (AmCo) and its subsidiaries, including AmCoastal, in April 2017, IIC in April 2016, and Family Security Holdings, LLC (FSH), including its subsidiary Family Security Insurance Company, Inc. (FSIC), in February 2015, and our strategic partnership with a subsidiary of Tokio Marine Kiln Group Limited (Tokio Marine), which formed Journey Insurance Company (JIC) in August 2018. Effective June 1, 2022, we merged JIC into AmCoastal, with AmCoastal being the surviving entity. Effective May 31, 2022, we merged FSIC into UPC, with UPC being the surviving entity.

As a result of underwriting actions implemented during 2023, as well as the receivership of our former subsidiary UPC by the DFS effective February 27, 2023, our policies in-force decreased by 91.0% from 254,275 policies in-force at December 31, 2022 to 22,848 policies in-force at December 31, 2023. Our 2022 value includes policies attributable to our discontinued operations.

Our business is subject to the impact of weather-related catastrophes on our loss and loss adjustment expenses (LAE). Over the last three years, the frequency of these catastrophes has increased. As a result, we have experienced increased catastrophe losses incurred during the prior three years. During the years ended December 31, 2023, 2022 and 2021, two, two, and four named storms, respectively, made landfall in our geographic footprint, resulting in retained pre-tax catastrophe losses of $729,000, $57,906,000, and $15,696,000, respectively, excluding discontinued operations. In addition, during 2022 and 2021, we increased our loss and LAE reserves as a result of development trends from 2017’s Hurricane Irma, that indicated our ultimate gross loss estimate should be increased.

The following discussion highlights significant factors influencing the consolidated financial position and results of operations of ACIC. In evaluating our results of operations, we use premiums written and earned, policies in-force and new and renewal policies by geographic concentration. We also consider the impact of catastrophe losses and prior year development on our loss ratios, expense ratios and combined ratios. In monitoring our investments, we use credit quality, investment income, cash flows, realized gains and losses, unrealized gains and losses, asset diversification and portfolio duration. To evaluate our financial condition, we consider our liquidity, financial strength, ratings, book value per share and return on equity.

AMERICAN COASTAL INSURANCE CORPORATION

Consolidated Net Income (Loss)

(1) Loss ratio, net is calculated as losses and LAE net of losses ceded to reinsurers, relative to net premiums earned. Management uses this operating metric to analyze our loss trends and believes it is useful for investors to evaluate this component separately from our other operating expenses.

(2) Expense ratio is calculated as the sum of all operating expenses less interest expense relative to net premiums earned. Management uses this operating metric to analyze our expense trends and believes it is useful for investors to evaluate these components separately from our loss expenses.

(3) Combined ratio is the sum of the loss ratio, net and expense ratio. Management uses this operating metric to analyze our total expense trends and believes it is a key indicator for investors when evaluating the overall profitability of our business.

(4) Underlying combined ratio, a measure that is not based on GAAP, is reconciled above to the combined ratio, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in “Definitions of Non-GAAP Measures”, below.

(5) Included in both the expense ratio and the combined ratio is amortization expense predominately associated with the AmCo and IIC acquisitions, which cause comparative differences among periods.

33

AMERICAN COASTAL INSURANCE CORPORATION

DEFINITIONS OF NON-GAAP MEASURES

We believe that investors’ understanding of ACIC’s performance is enhanced by our disclosure of the following non-GAAP measures. Our methods for calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Combined ratio excluding the effects of current year catastrophe losses and prior year reserve development (underlying combined ratio) is a non-GAAP measure, that is computed by subtracting the effect of current year catastrophe losses and prior year development from the combined ratio. We believe that this ratio is useful to investors, and it is used by management to highlight the trends in our business that may be obscured by current year catastrophe losses and prior year development. Current year catastrophe losses cause our loss trends to vary significantly between periods as a result of their frequency of occurrence and magnitude, and can have a significant impact on the combined ratio. Prior year development is caused by unexpected loss development on historical reserves. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our performance. The most directly comparable GAAP measure is the combined ratio. The underlying combined ratio should not be considered as a substitute for the combined ratio and does not reflect the overall profitability of our business.

Net loss and LAE excluding the effects of current year catastrophe losses and prior year reserve development (underlying loss and LAE) is a non-GAAP measure that is computed by subtracting the effect of current year catastrophe losses and prior year reserve development from net loss and LAE. We use underlying loss and LAE figures to analyze our loss trends that may be impacted by current year catastrophe losses and prior year development on our reserves. As discussed previously, these two items can have a significant impact on our loss trends in a given period. We believe it is useful for investors to evaluate these components both separately and in the aggregate when reviewing our performance. The most directly comparable GAAP measure is net loss and LAE. The underlying loss and LAE measure should not be considered a substitute for net loss and LAE and does not reflect the overall profitability of our business.

RESULTS OF OPERATIONS

Consolidated Results

Net income attributable to ACIC for the year ended December 31, 2023 increased by $779,766,000 to $309,911,000, compared to a net loss of $469,855,000 for the year ended December 31, 2022. The increase in net income was primarily driven by a decrease in loss & LAE for the year, as a result of Hurricane Ian making landfall in Florida in 2022, which caused large losses in 2022. In addition, we had an increase in our gross written premiums, an increase in ceded premiums earned, favorable prior year loss development during the year, decreased policy acquisition costs and general and administrative expenses, as described below.

Revenues

Our gross written premiums increased by $97,700,000, or 17.1%, to $670,043,000 for the year ended December 31, 2023, from $572,343,000 for the year ended December 31, 2022, driven by increased written premiums in Florida as we continue to grow our commercial book of business. This was offset by a decrease in written premiums across the personal lines business, driven by the cancellation of the quota share with our former subsidiary, UPC. The breakdown of the year-over-year changes in both direct and assumed written premiums by state and gross written premium by line of business are shown in the table below.

(1) We are no longer writing in Texas or South Carolina as of May 31, 2022.

(2) Assumed premium written for 2023 primarily included commercial property business assumed from unaffiliated insurers. Assumed premium written for 2022 primarily included personal property business assumed by our former subsidiary, UPC.

(1) Only includes new and renewal homeowner, commercial and dwelling fire policies written during the year.

(2) We are no longer writing in Texas or South Carolina as of May 31, 2022.

Ceded premiums earned increased by $88,057,000, or 33.1%, to $354,080,000 for the year ended December 31, 2023 from $266,023,000 for 2022. The increase is primarily driven by a $60,804,000 increase in ceded premiums earned from our quota share agreements. This increase can be attributed to the increase in AmCoastal’s quota share reinsurance coverage to 40% in the second quarter of 2023 from 10% during the first half of 2023. In addition, we saw increased costs associated with our Core catastrophe reinsurance program during 2023.

Net investment income increased by $2,901,000, or 37.8%, to $10,574,000 for the year ended December 31, 2023 from $7,673,000 for 2022, driven by increased interest income due to increased holdings and higher interest rates year-over-year.

35

AMERICAN COASTAL INSURANCE CORPORATION

Net realized investment losses and net unrealized gains (losses) on equity securities increased by $2,457,000, or 29.1%, to a net loss of $5,994,000 for the year ended December 31, 2023 from a net loss of $8,451,000 for the year ended December 31, 2022, driven by the liquidation of our fixed maturity securities in an unrealized loss position during 2022 to satisfy liquidity needs. The remainder of this change can be attributed to more favorable market conditions in 2023 resulting in decreased unrealized losses on our investment portfolio.

Expenses

Expenses for the year ended December 31, 2023 decreased $98,805,000, or 33.4%, to $196,811,000, from $295,616,000 for 2022. The decrease in expenses was primarily due to a decrease in loss and LAE as a result of Hurricane Ian making landfall in 2022, which caused a large increase in 2022. The calculations of our combined loss ratios and underlying loss ratios are shown below.

(1) Underlying loss and LAE is a non-GAAP financial measure and is reconciled above to net loss and LAE, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in the “Definitions of Non-GAAP Measures” section, above.

The calculations of the Company’s expense ratios are shown below.

Loss and LAE decreased by $71,944,000, or 53.4%, to $62,861,000 for the year ended December 31, 2023, from $134,805,000 for the year ended December 31, 2022. Loss and LAE expense as a percentage of net earned premiums decreased 27.7 points to 22.3% for the year ended December 31, 2023, compared to 50.0% for the year ended December 31, 2022. In addition, during the year ended December 31, 2023, prior year reserve favorable development was higher on both catastrophe and non-catastrophe losses. Excluding catastrophe losses and reserve development, our gross underlying loss and LAE ratio for the year ended December 31, 2023 would have been 9.4%, a decrease of 7.0 points from 16.4% during the year ended December 31, 2022.

Policy acquisition costs decreased by $11,972,000, or 12.6%, to $83,346,000 for the year ended December 31, 2023, from $95,318,000 for the year ended December 31, 2022. The primary driver of the decrease in expense was an increase in ceding commission of $36,457,000, driven by the changes in the terms of our quota share reinsurance agreements. This was partially offset by increased external management fees and premium taxes of $21,199,000 and $1,949,000, respectively, both of which fluctuated in conjunction with the year-over-year increase in commercial lines gross written premium.

36

AMERICAN COASTAL INSURANCE CORPORATION

Operating and underwriting expenses decreased by $3,489,000, or 25.4%, to $10,240,000 for the year ended December 31, 2023, from $13,729,000 for the year ended December 31, 2022, driven by decreased costs such as printing, postage, rent and utilities totaling $1,384,000 as we look to reduce our overhead spending. In addition, investments in technology decreased $1,834,000 year-over-year.

General and administrative expenses decreased by $12,792,000, or 30.3%, to $29,489,000 for the year ended December 31, 2023, from $42,281,000 for the year ended December 31, 2022, driven by the impairment of goodwill attributable to the Company’s personal lines operating segment during 2022 totaling $10,157,000. There were no similar transactions in 2023.

We experienced favorable reserve development in the current year and its historical impact on our net loss and net underlying loss ratios is outlined in the following table.

(1) Underlying net loss and LAE Ratio is a non-GAAP measure and is reconciled above to the Consolidated net loss and LAE Ratio, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in the “Definitions of Non-GAAP Measures” section, above.

Commercial Lines Operating Segment Results

Pretax earnings attributable to our commercial lines operating segment for the year ended December 31, 2023 increased by $82,287,000 to pretax income of $118,128,000, compared to pretax income of $35,841,000 for the year ended December 31, 2022. The increase in pretax earnings was primarily due to an increase in revenue driven by increased gross written premium described below. This was partially offset by increased ceded premiums, driven by the changes in our quota share contracts. In addition, all of our expenses related to commercial lines decreased year-over-year, as described below.

Revenues

Our gross written premiums attributable to our commercial lines operating segment increased by $127,466,000, or 25.1%, to $635,709,000 for the year ended December 31, 2023, from $508,243,000 for the year ended December 31, 2022, driven entirely by increased written premiums in Florida as we continue to focus on increasing commercial written premiums and transitioning to a specialty commercial lines underwriter. These increases were partially offset by a decrease in assumed premiums as we wind-down these contracts, as well as a decrease in premiums written in Texas and South Carolina, as we are no longer writing business in these states. The breakdown of the year-over-year changes in both direct and assumed written premiums by state are shown in the table below.
